CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER

FEATURES

GENERAL DESCRIPTION

■ Wide Operating Voltage Range: 1.5V to 15V

■ Boost Pin (Pin 1) for Higher Switching Frequency

■ High Power Efficiency is 96%

■ Easy to Use – Requires Only 2 External Non-Critical

Passive Components

The TC7662B is a pin-compatible upgrade to the Indus-

try standard TC7660 charge pump voltage converter. It

converts a +1.5V to +15V input to a corresponding – 1.5 to

– 15V output using only two low-cost capacitors, eliminating

inductors and their associated cost, size and EMI.

The on-board oscillator operates at a nominal fre-

quency of 10kHz. Frequency is increased to 35kHz when

pin1isconnectedtoV+, allowingtheuseofsmallerexternal

capacitors.Operationbelow10kHz(forlowersupplycurrent

applications) is also possible by connecting an external

capacitor from OSC to ground (with pin 1 open).

■ Improved Direct Replacement for Industry Stan-

dard ICL7660 and Other Second Source Devices

APPLICATIONS

■ Simple Conversion of +5V to ±5V Supplies

■ Voltage Multiplication V_OUT= ±nV_IN

■ Negative Supplies for Data Acquisition Systems

and Instrumentation

■ RS232 Power Supplies

■ Supply Splitter, V_OUT= ±V_S/2

The TC7662B is available in both 8-pin DIP and 8-pin

small outline (SO) packages in commercial and extended

temperature ranges.
